DJ Khaled, who is clearly up to something, had a major weekend.

After buying a $10 million Beverly Hills mansion and announcing that his forthcoming album is on the way, the producer/social media mogul hit the lab with three superstars—Chance the Rapper, Justin Bieber, and Alicia Keys.

On Saturday (Jan. 14), Khaled let fans know that he’s “up to something” with Keys. The two appeared in Snapchat videos together and Alicia even posed for a photo with the producer’s new son, Asahd, who serves as the album’s executive producer.

The following day, Khaled joined Justin Bieber for a quick game of street hockey at the pop superstar’s home. “This is a new sport for me,” Khaled said while Bieber scored a flurry of goals. “This my boy Justin Bieber. We up to something.”

As if that wasn’t enough, Khaled then hit the lab with Chance the Rapper. Sharing a photo of Chano in the recording booth, Khaled revealed just a portion of his top secret operation.

“Fan luv here’s a update,” he wrote. “@chancetherapper is in the booth ! FAN LUV REMEMBER EVERYTING TOP SECRET !!”

Last week, Khaled announced that his Major Key follow-up is on the way. “I’m releasing the title of my new album soon,” he said. “I can say soon. Soon come!”

Released last year, Major Key became Khaled’s first No. 1 on the Billboard 200. Featuring artists like Drake, Jay Z, Nicki Minaj, Kendrick Lamar, Lil Wayne, Nas, J. Cole, Wiz Khalifa, Rick Ross, and Future, the album sold 95,000 equivalent album units in its first week.
